Public predicates

digest/2

Computes the digest for a list of bytes and returns it as a list of bytes.

Compilation flags:
static
Template:
digest(Bytes,Digest)
Mode and number of proofs:
digest(+list(byte),--list(byte)) - one

digest_size/1

Returns the digest size in bytes.

Compilation flags:
static
Template:
digest_size(DigestSize)
Mode and number of proofs:
digest_size(--integer) - one

block_size/1

Returns the hash block size in bytes.

Compilation flags:
static
Template:
block_size(BlockSize)
Mode and number of proofs:
block_size(--integer) - one
